HP reincarnate old ink cartridges as key part for new printer
Here’s a fun use for discarded ink cartridges: turn them into the printhead of a new printer.
That’s
what Hewlett-Packard has done with its HP Photosmart D5460. The
printhead of the new product is made up of 55 percent recycled PET
plastic, which is made out of ink cartridges collected as part of the
HP Planet Partners program. The D5460 also comes with a pretty cool
software feature called Smart Web Printing that lets you adjust pages
you’re printing from the Internet so that you can define exactly what
you want and don’t want up printing all sorts of extra pages with
extraneous content on them.In terms of eco-savvy materials, the new
Photosmart model is a pale shadow, though, of the HP Deskjet D2545,
which is made ALMOST ENTIRELY out of recycled plastics. (Something like
83 percent of the printer’s total weight; plus, it uses cartridges that
are themselves made from recycled plastic resin.)
